Enroll your Device
I want to:

- Enroll: Duo Mobile on Smartphone or Tablet
- Enroll: Hardware Token (DUO)
- Enroll: Backup Device
- Enroll: Yubikey OTP (self configuration guide no UCSC support)
Enroll: Backup Device
It is strongly recommended that you add an additional device to serve as a backup. The device can be another smartphone, tablet, hardware token or even a trusted family/friend's smartphone.
Not enrolling a backup device puts you at a high risk of losing access to Gold systems if your primary device is not available.
Instructions for enrolling a backup device can be found at the Add or Manage Devices page.
